The 16×9 Kong Quick Release Adapter for Easyrig w/ 1/4-20 Eyebolt is an add-on accessory for Easyrig support vests that enables quick attachment and detachment of camera rigs. An eye bolt screws into 1/4-20 insets found on common camera cages, which then slips into an aluminum clamping mechanism for a secure hold that can quickly be decoupled with one hand. Your camera rig will need a 1/4"-20 threaded hole to attach the bolt.
We also carry an alternate version of this adapter with a 3/8-16 eyebolt which can be found here.
